The mouth is a sexual organ. The man inserts his lewd, slick tongue into the other man's mouth and strokes it all over. Or he intertwines his tongue with the other man's and melts it into a sticky mess. He exchanges saliva and feels a sense of conquest as he paints the other man's body with his own color. The most exciting part of a kiss is when it is exchanged between a beautiful woman or young girl and an old man. Being soiled by a middle-aged man really brings out the beauty and prettiness of the woman. Of course, he also inserts his tongue into the lower mouth, resulting in a sloppy double bond between the beautiful woman and the old man in this 8-hour kissing session.
